Supply ventilation via inline fan and return duct
6 Replies

I am looking for a mechanical ventilation solution that is a step above the single supply or exhaust fan which is set to the required 62.2 rate. On the flip side, it must be something that is similar…Continue

Combined combustion tester CO + Manometer

Wondering if anyone has any feedback on the combustion analyzers that have integrated pressure measurements. I am getting ready to move to two crews and do not want to buy a separate manometer as we…Continue

Insulation/venting/air barrier for cathedral ceiling
21 Replies

I have a client who has built a home that is ready for insulation. That said - it is what it is and I am not looking for what should have been done - there will be no reconstruction. We are the…Continue

Easy Tests for HVAC during audit

I was looking to beef up my offerings for standard energy audit and feel like some quick screening tests for HVAC would be great. The only test I currently do is a dominate duct test. Since I am…Continue

"I agree and studies done will agree with you in those cases too - it makes sense when there is little to no insulation in the wall. You got a bigger piece of pie to bite from. Small pie, small bite."

"In this scenario the walls were made of R35 rigid foam. Even if ex-employee of big energy company calculated a 50% reduction in heat transfer through the walls(and was accurate), that in itself doesn't mean anything. 50% of barely anything, is…"

"Actually emissivity rating doesn't make much of a difference between coatings because almost all coatings (and all construction materials except clean bare metals) have an emissivity value around 0.9. Anyways, your example still doesn't…"

"Have you ever taken a 'rule of thumb' measurement of how many degrees from ambient standard white paint would be? Seems like that would be the real test of the effectiveness of the RCC paint. Another interesting test would be how much the…"

"And how much of that 1.7% of the suns energy that got through the RB or RCC gets into the house, will depend on the R-value of the insulation in the ceiling."

Craig Bird commented on Hal Skinner's group The RCC Classroom (Radiant Control Coatings)
"Hal - I would disagree that radiant heat "goes through" fibrous insulation. Radiant heat transfers only through air. When it hits a solid, it is either absorbed or reflected. Since fibrous insulation does not have a very high reflectivity,…"

"Now back to your question - the best data for radiant barriers is the DOE studies from the ORNL. Just google "Radiant Barrier Fact Sheet". As far as a comparison for a sheet radiant barrier compared to a foil faced rigid board, I refer you…"

"Kurt - Radiant heat transfer does not heat the air. It is the passing heat directly from hot object to cold object. The hot object heats the cold object directly through infrared heat transfer. Think about it -  the heat we get on the earth is…"

The RCC Classroom (Radiant Control Coatings)

A group where energy professionals can learn about all the different energy saving aspects of RCCs.  I have worked with one particular RCC for 30 years.  I have amassed alot of information I can share.  Everyone knows, accepts and understands how RCCs work as a 'Cool Roof' coating.  However, that seems to be where the knowledge on these products different energy saving applications abruptly stops.  I hope to change that with this group. There are over 300 protective coatings out there and they…See More
